There are many things that you have to take into consideration. You have to think of your lead time and everything that goes into it. Also consider receiving time at Amazon. It might take awhile for them to check it in. When planning a strategy for your FBA inventory, you should plan for the worst case scenario. There could be issues with it getting backed up at port or issues with your supplier.
A great thing about using software for forecasting, is that they can keep track of that, whether it’s Jeremy’s Forecastly or another piece of software. It tracks inbound inventory, current inventory, what you have in manufacturing, and true sales velocity.
You also need to consider spikes in sales. You may have consistent sales every day, but a couple times a month your sales spike. This is why you need to build in a safety stock. That gives you a cushion so that if you get a surge in sales, you have enough stock to cover it until your next shipment gets there.
Forecastly has many business that use its service. The software can then use this anonymous data to make predictions about Amazon as a whole. It takes ASIN level data over the past 30, 60, and 90 days to makes prediction about future sales numbers.
Their main focus is demand forecasting. It considers your recent sales including stock out periods. If you were out of stock, it can determine what you would have sold had the product been available. It also tracks the variability of demand which is something you can’t do in a spreadsheet.
The main thing you have to be conscious of when managing your FBA inventory is, what do you need to replenish, when do you need to replenish it, and how many units do you need to replenish. Forecastly tracks all that while monitoring your inventory and will recommend your orders.
Many sellers want to use a 60 day trend to determine their sales velocity which is a bad idea. If you selling in an upward trend, meaning your sales are growing, then your sales were much lower 60 days ago. This will make your average too low. Forecastly uses a 30 day trend to get the most up to date projections.
We, here at Amazing FBA, love a rule of thumb. Unfortunately, when it comes to FBA inventory, many sellers follow a rule of thumb that won’t help them, and could hurt them. It’s the idea that you need to have X amount of days worth of inventory. Whenever they place their order, they bring it back to this magic number.
For example, if you wanted to maintain 90 days of inventory and you order monthly with a 30 lead time. When it’s time to make an order, you have 60 days of inventory. Based on this, you would order 30 days of inventory.
You don’t need that much inventory. You wouldn’t need to order for another month because you have a 30 day lead time and you’re tying up cash in stock you don’t need. The rationale behind this method is security. The attempt to avoid stock outs by keeping a large amount of stock on hand.
Amazon will continue growing their own private label brands. So Amazon is now your competitor. International markets are growing. The European markets are booming. If you’re having success in the US, you’ll want to take those products to the UK and the rest of Europe. That isn’t as easy as it sounds. You have to come up with a separate replenishment strategy as well as deal with the tax regulations. There is an opportunity, though. Especially in Germany where 40% of the sellers are non-German, and very few are American. That means they are willing to buy from foreigners, but not many Americans are there yet.
As Amazon grows, the more warehouse space they will need. They are investing in new space, but they don’t want to overdo it. You will likely see seller-fulfilled-prime see some growth as a solution to this problem though will come with its own issues.
The inbound process is likely to change. It used to be that you would just slap on a UPS label. Then you had to also do the Amazon label. Now you have to do box contents. It’s going to get more and more complicated as Amazon continues handling more inventory.
